Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

As for someone who's taking physics without pre-calc, radicals are Greek. This video did nothing but overwhelm me

[@elizabethv515]

Rinzler SAME

[@Isura101]

I am so sorry dude. This is my bread and butter. I loved it in high school. I loved it in university. And i love it in my current job. I am back for a refresh! after so many year. This mans voice is of an angel. Please keep doing examples. The more you practise, it will become second nature. Just like everything else in life. God speed.

[@Anushka-ey8pc]

um im in grade 9th and you're going to college. I've finished calc you've not done calc. just look at the difference

[@lucyien3843]

who tf let you take phys but not pre cal

[@mafia6330]

"Similurlurly" lmao gets me every time

[@codythompson9973]

When I do the practice problems on the site, the x and y values are mixed up for some reason. One time, the opposite side of the of the triangle was done as the x axis somehow. I'm doing the calculations right, but I cannot tell if the site is doing it wrong or if I am. Most likely I am.

[@neelchat594]

Thank you Sir!

[@MZ-lm5ei]

very nice video thank you

[@mariahasan6410]

Thankyou so much 👍

[@songs3444]

What is the program that you used? Plus, the video is very helpful.

[@divyachoudhary2075]

Nice

[@humawaseem576]

on 5:29 how did you get 2 cos 45? thanks

[@Unknown.20]

180-134

[@socialresponsibility3148]

What app he used?

[@hilinaabay9510]

why dont we use phaytagoras to add a and b

[@pearse1072]

It isn’t a scalar measurement

[@awaansiddiqui8215]

That gives only the magnitude

[@ahmedlakhi4136]

stoppp saying something like that

[@devarshsomani385]

the tail and the arrow were wrong two arrows never meet each other it's always tail to arrow and vice-versa

[@brandrixco6246]

Why is it false? When you do vector addition both a and b always meet arrow to arrow to form c. | Example www.onlinemathlearning.com/image-files/xadd-vectors.png.pagespeed.ic.oXon4PhQcs.png

[@cekdarakkurt3257]

In my opinion this is too complicated explaind

[@deankaraniya7422]

It isn't, you just didn't have the sufficient prerequisite knowledge.

[@noiritanath6008]

​@@deankaraniya7422 would you mind revealing the pre- requisites, so that one could understand vector? If you do, it would be a great help

[@joseffinn5836]

I find this explanation way too complicated...

[@animusfoxx6965]

PLEASE, *stop* repeating yourself. You said "might look something like" 3 times, and I know you are trying to stray away from dead air, but it is really grating on the ears to listen to somebody repeat themself this many times, and in a set of videos that hundreds of students are forced to listen to for school, it is not acceptable to be doing something this infuriating. Fix this.

[@iwantmynameback5999]

Paul Driftmier Please get over yourself, no one is going to fix anything as insipid as that.

[@miesht430]

Yes thank you i had to keep pausing the video to stop getting annoyed...its okay if theres a bit of silence in the vid but hearing the same thing over and over is so frustrating

[@miesht430]

as students, if this is the type of explanation that helps us, we have the right to ask for an easy to follow video, not something that frustrates us on top of our already stressed minds...especially from khan academy they usually produce great content

[@miesht430]

Calm tf down
